FLY-EXIT FOR WINDOW AND DOOR SCREENS- Specification of Letters Patent.

Patented May 14, 1907.

Application filed July 27,1906- Serial No. 328,113-

To aZZ whom it may concern:

Be it known that we, WILLIAM H. PHILLIPS and ORA G. WILLIAMS, citizensof the United States, residing at Sacramento, in the county ofSacramento and State of California, have invented certain new and usefulImprovements in Fly-Exits for Window and Door Screens, of which thefollowing is a Specification.

Our invention relates to devices in the nature of fly exits for windowand door screens and has for its object the provision of a device whichcan be readily attached to screen frames in common use, the deviceconsisting of a number of separate overlapping units capable ofattachment to the top of the window or door screen frame of ordinary construction.

The construction and advantages of my invention will be described indetail hereinafter and illustrated in the accompanying drawings inwhich- Figure 1 is a view of the upper fragment of a door or windowscreen frame showing my improved exit in position, Fig. 2, a cross sectional view, and Fig. 3, a detail view of the exit sections.

In the drawings similar reference characters indicate correspondingparts throughout the several views.

A represents the frame of a screen door or window having the screenfabric B cut away at the upper end leaving an opening C at the top ofthe frame. The exit D consists of one or more plates of Sheet metal Esecured in opening 0. Each of said plates E has its middle portioncurved inwardly as shown at F. The upper edges of plates E are formedwith a flat portion G and have angular ears H integral therewith andsecured to frame A. The lower edge of each plate E is also formed flatas shown at I against which the top of screen fabric B rests. Jindicates ears formed by extending the outer edge of the outer sec tionplates E opposite the flat portions I which are secured to the siderails of frame A.

The edges of plates E are bent back on themselves as shown at K, one ofthe end plates having the bent back portion for its whole length whilethe other plates have the bent back portion at one end cut away so thatthe single thickness of metal may slip" in between the bent back portionand the body of the plate on the adjoining section.

It will be understood from this construction that the exit D may beadjusted to fit any length of opening C by taking the num ber of platesnecessary to approximately fill the space and then adjusting them bysliding them on one another so as to completely fil the space. Ifdesired a strip of screen fabric or other material L may be secured onthe inner side of the frame A over exit D so as to form a chamber M butthis is not essential to a successful operation of our invention as itwill be understood that the insect in crawling up the screen will bevattracted by the light coming through the opening between flat portion Gand the frame A and will crawl therethrough and out of the room.

Having thus described our invention what we claim is 1. In combinationwith a frame, and a screen fabric secured thereto with an openingbetween its to' edge and the top rail of the frame, a plura ity ofplates secured in said openin having their edges bent back on themselvesto form slidcways, a part of said bent back portion on the plates cutaway to fit the slideway on an adjacent plate, the central longitudinalportion of the plates bent inwardly leaving the upper and lower edges 4cure them to the side rails of the frame, sub-- stantially as shown anddescribed.

2. In combination with a frame, and a Screen fabric secured thereto withan opening between its to edge and the top rail of the frame, a pluraity of plates secured in said opening having their edges bent onthemselves to form slideways, a part of said bent back portion on theplates cut away to fit the slideway on an adjacent plate, the centrallongitudinal portion of the plates bent inwardly leaving the upper andlower edges flat, angular ears projecting from the upper edge of theplates to space them away from the top rail of the frame, earsprojecting from the lower edges of the end plates to secure them to theside rails of the frame, and a strip of fabric secured over said platesand forming a chamber therewith, substantially as shown and described.

3. In combination with a frame, and a screen fabric secured thereto withan opening between its to edge and the top rail of the frame, a pluraity of plates secured in said opening having their central longitudinalportions bent inwardly leaving their upper and lower edges flat, one ofsaid plates havextending from the lower edges of the end mg its flatsurfaces bent back on themselves lates to secure them to the side I L1lSof the for its entire length to l'orm shdeways, the ram.e,substnnt1allyas shown and described.
